Stuff and nonsense
"The joy of Gadget Ads is that they are interactive and fun without being intrusive"
There's no such thing.
Anything which involves animation and audio will, by definition, INTRUDE.
Hopefully though, somebody will rapidly come up with a firefox extension that blocks them. So that the advertisers actually get LESS for their money than they would have done if they'd used elementary common sense and stuck to plain, genuinely non-intrusive, HTML.
